  • 1. ISM Millionaire Challenge DNA

2. #1What does the acronymDNA stand for?A: Deoxyribonucleic Acid B: Dimethylene AcidC: Distilled Nucleic AcidD: Double Nucleic Acid 3. A. DNA= deoxyribonucleic acid is a long molecule that is present inbasically every cell of nearly all living organisms and contains the geneticinformation for those organisms. 4. #2 Which of these is .NOT a base in DNA?A: CytosineB: UracilC: Guanine D: Thiamine 5. B. UracilUracil is onlyfound in RNA 6. #3 In the ladder analogy of the DNA molecule, the "rungs" of the ladder are:A: SugarsB: PhosphatesC: Joined sugar andD: Paired basesphosphates 7. D. Paired bases 8. #4 How many bases does it take to makea codon for a protein?A: one B: twoC: three D: Number can change 9. C. Three3 adjacent bases from the RNA sequence 10. #5 Which of the following base pairs would not be found in a cell?A: adenine thymineB: cytosine guanineC:thymine uracilD: thymine adenine 11. C. thymine uracilUracil is single stranded (RNA)so it never has a base pair 12. #6 The structural shape of DNA is, ofcourse, the famous double helix. What isa "double helix"?A: Two Y-shaped strand B:Two loops, like a figure eightC: Two spirals, like a twistyD: Two X-shaped strands ladder 13. C. Two spirals,like a twisty ladder Letter D. Two X-shaped strands iswrong. This is a chromosome, which isa lot of double helix DNAs packedtightly together 14. #7 DNA regularly undergoes changes to its sequence that can be inherited or cause diseases (for example, cancer).This is known as?A:Methylation B:ReplicationC: Mutation D: Transformation 15. C. mutationAny change in the gene sequence,which can be caused by radiationand chemicals or just be a randommistake 16. #8What kind of mutation results in thereplacement of one amino acid for another?A: Frame Shift B: ChromosomalC: SubstitutionD: Deletion 17. C. SubstitutionAlso known as a point mutation. Thenumber of bases is not changing (likein a frame shift or deletion) so only 1 codon and 1 protein is affected. 18. #9Which one of the following is NOT acommon characteristic of both RNA andDNA?Both contain C & GA:They are both nucleicB: bases in their sequences. acids.Both contain A & T basesC: Both can be found in theD: in their sequences. nucleus 19. D is correct. Only DNA contains A & Tnucleotide bases in the sequence; RNA does not have Ts 20. #10 Although most mutations are harmful, sometimes a beneficial mutation occursthat helps an organism do what?A: Increase its amount of B: Live shorter, happierDNA. lives. Be better adaptedC: Grow faster. D: to its environment. 21. D. Be better adaptedto its environmentso that it can survive longer byescaping predators or getting preyeasier 22. #11What is one way that RNA differsfrom DNA?A: RNA contains a different B: RNA occurs only in the kind of sugar nucleus.C: RNA is a longerD:DNA contains only 3 molecule. nitrogenous bases. 23. A. RNA contains adifferent kind of sugarR stands for ribose, which is differentfrom deoxyribose found in DNA 24. #12Our individual DNA makes us unique, but it also makes us human. What percentage of our DNA do humans have in common withour closest primate cousin, the chimpanzee?A: Over 60 percent B:Over 89 percentC: Over 98 percent D:Over 99 percent 25. C. Over 98 percent Humans share over 98 percent of theirgenes with the chimpanzee.The remaining 2 percent allows us to takequizzes. 26. #13An original DNA base sequence is ATTCCG. What would be the corresponding RNA base sequence?A: AUUCCG B: TAAGGCC: ATTCCG D: UAAGGC 27. A. AUUCCGthere are no Ts in RNANeed to copy DNA using base pair rules 28. #14 To whom is the discovery of the structure of DNA credited?A: Charles DarwinB: Gregor MendelC: Alexander Fleming D: Watson & Crick 29. D. Watson & Crick 30. #15 Human DNA is located primarily in the nucleus of each cell, but small amounts can also be found in which other part of the cell?A: MitochondriaB:RibosomesC:Cell WallD:Cytoplasm 31. A. MitochondriaSmall amounts of DNA are also housed inthe cells mitochondria, whose mainfunction is to generate the energy neededfor the cells functioning. It couldnt be in the cell wall, because human cells arebound by membranes and lack the cellwalls that plants have. 32. Great Job!!!!Thank you for playing!
